- the support part 6.2 is located however, is still in its initial state and takes the maximum possible distance from the base part 6.1.
- the Pliers stamp 7.3 due to their guided in the oblique guides 7.5 Guide leg 7.6 against the force of their compression springs 7.4 in addition to Lowering movement directed towards the tube 2 from, so that their working surfaces 7.8 the radiant sheet 1 to the circumference of the tube 2nd pressed, as can be seen in FIGS. 8 and 9. In the final state they were Stop surfaces 7.9 of the legs 7.7 on the strip-shaped elevation 6.6 of the pipe holding part 6.4, so that there was a positive end position.
- Fig. 9 a situation is drawn in which the upper tool 7 with the Press stamp 8 has returned to the starting position. In this The pipe 2 surrounded by the radiant sheet 1 is clearly visible. The Fig. 9 also shows that the support part 6.2 due to the force of the Compression springs 6.3 has returned to its original position.
- FIGS. 11 and 12 This next pressing process is shown in FIGS. 11 and 12 by two successive steps are shown.
- Fig. 11 is another lowering the press die 8 provided with the upper tool 7; the Fig. 12 shows the situation at the end of the second pressing process, after which Execution a second pipe 2 is encompassed by the radiant sheet 1.
